It sends the password, not really reasonable for it to only be able to authenticate one Wi-Fi device if another Wi-Fi device is still present. Wi-Fi passwords aren't really that secure a thing these days, anyways. If you need your Wi-Fi to be secure, you need to be doing RADIUS authentication or similar. It's just from a UI standpoint that it's very seamless. You don't have to see the password, you don't have to enter it anywhere, one device just shares the Wi-Fi password with another device nearby.
